Eggs: Depending on the mosquito genera there are different types of eggs. Aedes is a so-called floodwater mosquito that occurs in areas that have a dry and wet period like pastures. They lay their eggs on damp ground that will be flooded later. Therefore those eggs have to withstand the dry period. Some of them can hatch after being dormant for over 20 years. The other three genera lay their eggs on the surface of stagnant water, where they hatch within 1-2 days. Culex and Culiseta mosquitoes lay them in clumps of about 100-300 eggs, the so-called egg rafts, which float on the water. Anopheles on the other hand, lay single eggs, which each has individual floating devices on the sides.

 Larvae: The larvae develop in four stages.
